I've had a bonsai for at least half a decade, its grown, i feed it every so often, i never tried to shape it or do anything with it. I'm just glad its survived me this long, but i like the plant. I keep it above the sink so its really in my face to remind me about it. Long story short, i suppose you can be a really lazy bonsai owner, but in my defence it was a gift.
I appreciate this comment is likely wide of the margin on the 'helpful' front, sorry.
